spiritual motherhood of Mary

In what way is the spiritual motherhood of Mary universal? Mary had only one Son, Jesus, but in him her spiritual motherhood extends to all whom he came to save. Obediently standing at the side of the new Adam, Jesus Christ, the Virgin is the new Eve, the true mother of all the living, who with a mother's love cooperates in their birth and their formation in the order of grace. Virgin and Mother, Mary is the figure of the Church, its most perfect realization.
